ATLANTA (July 19, 2013)--A construction crew unearthed what appeared to be a cannonball near Centennial Olympic Park in downtown Atlanta, police said.
Police spokesman Gregory Lyon said the crew dug up the suspected cannonball Thursday afternoon.
Authorities took it to a bomb range.
Centennial Olympic Park is owned by the Georgia World Congress Center Authority whose spokeswoman Jennifer LeMaster confirmed the cannonball was removed from the property.,
Authorities have not yet determined exactly how old it is.
Police spokesman John Chafee said bomb technicians think the artifact may have been from the Civil War era, but it has yet to be examined by an expert.
When federal troops besieged Atlanta in 1864, they fired thousands of cannon shells into the area that now includes Centennial Olympic Park.
Gordon Jones, the Atlanta History Center's senior military historian and curator, said it could have been fired by federal soldiers from outside the city in an effort to strike the railroad roundhouse, a key military target, or he says, it could have been a Confederate cannonball that was simply left behind.
